But that's because it could *block* other queries. Not because it should be
causing deadlocks. Unless you're doing analyze within a transaction I don't
see why a autovacuum would be causing deadlocks. There are useful reasons to
run analyze within a transaction but I suspect you're not actually doing it
for any of those reasons.
